                                    PART I


ITEM 1.  DESCRIPTION OF BUSINESS

UNITED SECURITY BANCORPORATION

United Security Bancorporation (Company) is a multi-bank holding company
headquartered in Spokane, Washington.  The Company owns two banks, United
Security Bank (USB) and Home Security Bank (HSB) (collectively, Banks), and
also owns USB Insurance (an insurance agency), USB Leasing (a leasing company),
and USB Mortgage (a mortgage company).  The Company conducts its banking
business through ten branches located in communities throughout eastern
Washington, including Spokane.  The Company focuses its banking and other
services on individuals, professionals, and small to medium sized businesses in
diversified industries throughout its service area.  At December 31, 1995, the
Company had total consolidated assets of $191.8 million, net loans of $141.9
million and deposits of $163.8 million.  The Company was founded in 1983 and
has been profitable in every year since its inception.  In 1995, the Company
completed a public offering selling $8.5 million in stock and is now listed on
NASDAQ under the symbol "USBN".

THE BANKS

USB serves customers in Spokane and northeastern Washington from seven
branches.  HSB serves customers in southeastern Washington from three branches. 
The Banks offer a full range of financial services to commercial and individual
customers, including short-term and medium-term loans, revolving credit
facilities, inventory and accounts receivable financing, equipment financing,
residential and small commercial construction lending, agricultural lending,
various saving programs, checking accounts, installment and personal loans, and
bank credit cards.  The Banks also provide a broad range of depository and
lending services to commercial, industrial and agricultural enterprises,
governmental entities and  individuals.  The Banks' deposit-taking and
lending activities are primarily directed to the communities in which their
branches are located.  The Banks' primary marketing focus is on small to
medium-sized businesses and professionals in these communities.

The loan portfolios of the Banks consist primarily of commercial, agricultural,
real estate (both mortgage and construction loans) and installment loans.  At
December 31, 1995, virtually all of the loans originated by the Banks were
within the Banks' principal service areas.

The Company is committed to the needs of the local communities it serves, and
strives to provide a high level of personal and professional service to its
customers.  Management believes the Company's community involvement, its
understanding of its service area and its local decision-making abilities give
it a distinct advantage over larger banking institutions.  The Company is well
positioned to provide loans to small and medium sized businesses because of the
Company's direct knowledge of its customers' businesses and the communities it
serves.  USB and HSB provide personalized, quality financial service to its
customers, which has enable them to maintain a stable and relatively low-cost
retail deposit base.

USB INSURANCE

USB Insurance began operating in April 1987 and is engaged in selling a full
line of insurance and financial products such as annuities and mutual funds on
an agency basis to individuals, commercial, industrial and agricultural
enterprises from locations in Colville, Chewelah and Kettle Falls, Washington. 
Its business was significantly enhanced in 1990 through the acquisition of two
additional agencies in northeastern Washington.  Total revenues of USB
Insurance for the year 




                                      3

                        UNITED SECURITY BANCORPORATION

ended December 31, 1995 were $1,303,000 as compared to revenues of $1,288,000
for 1994.  The insurance operation was profitable for the first time in 1995. 
It incurred losses for the past four years primarily because of amortized
expenses associated with noncompetiton agreements entered into in conjunction
with its agency acquisitions.

USB LEASING

USB Leasing began operation in 1986 and is engaged in equipment leasing to
small and medium-sized companies in the markets it serves.  The Company has
used a portion of the proceeds from its May, 1995 stock sale to expand its
leasing operations.  Leasing assets grew to $1.5 million as of December 31,
1995 from zero as of December 31, 1994.  Management of the Company expects to
continue expanding its leasing business over the next several years.

USB MORTGAGE 

In 1995 the Company provided USB Mortgage with a portion of the proceeds
received in a public offering of the Company's common stock in 1995. 
Management expects to continue expanding its mortgage business over the next
several years.  As of December 31, 1995 assets were $545,000.

BUSINESS STRATEGY

The Company's business strategy is to continue to build a growing, profitable
community banking and financial services network by emphasizing high quality
customer service and by focusing on the financial needs of consumers and small
to medium-sized businesses.  The Company intends to pursue an aggressive growth
strategy, the key components of which include:

    o  Increasing market share in existing markets
    o  Expanding the markets served through new branch openings and acquisitions
    o  Expanding nonbanking financial services
    o  Providing superior customer service

Increase Market Share in Existing Markets.  Since its formation in 1983, the
Company has focused on commercial banking to small and medium-sized businesses,
professionals and other individuals.  Management believes that the Company can
continue to gain market share by targeting products and services.  To augment
this strategy, the Banks have recently opened branches in downtown Spokane and
Yakima, Washington.

The Company emphasizes the development of long-term relationships with its      
customers, which enables the Banks to develop and offer new products that meet
its customers' needs.  The Company is oriented toward the communities it serves
and is actively involved in these communities.  The Company believes this
community orientation gives the Company a competitive advantage in attracting
and retaining targeted customers.

The consolidation of the banking industry in recent years has resulted in
centralized loan approval and servicing functions in the larger financial
institutions with whom the company competes.  This has resulted in
inconvenience and reduced service to small business and individual customers of
these institutions, and has created opportunities for smaller, locally-focused
institutions, such as Banks, which can approve credit and offer other
customized banking services within each branch.  The Company maintains loan
officers in each branch, and branch managers have the authority to approve
loans in amounts up to $100,000.  Although loans are monitored and serviced at
the borrower's branch, the Company has centralized all note and collateral
documentation to decrease costs and standardize procedures.

                         UNITED SECURITY BANCORPORATION

Expand Markets Served through New Branch Openings and Acquisitions.  The
Company intends to expand its presence in eastern and central Washington by
opening new branches and acquiring other financial institutions in markets not
currently served by USB or HSB.  Management has recently opened branches in
Spokane and Yakima.

Management considers a variety of criteria in evaluating potential branch
expansion, including the demographics and short and long-term growth prospects
for the location, the management and other resources needed to integrate the
branch into its existing operations, the degree to which the branch would
enhance the geographic diversity of the Company or would enhance the Company's
presence in an existing market, and the estimated cost of opening and operating
the branch as compared to the cost of acquiring an existing office and deposit
base.

In addition to internal growth, there may be attractive opportunities to grow
the Company through carefully selected acquisitions of other financial
institutions or their branches in central and eastern Washington.  Management
believes that the continued consolidation of the banking industry will result
in attractive acquisition opportunities.  No acquisition negotiations currently
are in progress, nor does the Company have any agreements, either written or
oral, with respect to any acquisition opportunity.

Expand Nonbanking Financial Services.  The Company intends to aggressively
expand the nonbanking products and services offered through USB Insurance, USB
Leasing, and USB Mortgage, and expects to develop other products and services,
including real estate-related financial services not currently offered through
the Banks.  USB Insurance will seek to expand its emphasis on marketing a full
line of insurance and financial products such as annuities and mutual funds to
individuals and commercial enterprises, and USB Leasing will continue to focus
on providing commercial leases to small and medium-sized businesses that
utilize computers, heavy, non-specialized, industrial equipment, and
agricultural equipment.  Management believes the expansion of the Company's
customer base through growth and possible acquisitions should create
significant new opportunities for each of the nonbank subsidiaries to
cross-market their products and services.

Under current federal regulations, the Company is precluded from maintaining    
offices for USB Insurance in any Bank branch serving a community of more than
5,000 inhabitants.  As a consequence, the products and services offered by
these subsidiaries are necessarily limited to the smaller communities in the
Company's service areas in which the Banks maintain branches.  When regulations
limiting these nonbanking activities are relaxed, however, the Company expects
to integrate USB Insurance throughout its community banking network.

Provide Superior Customer Service.  The Company attributes it success to its
efforts to offer superior, personal service through professional bankers at all
of its branches.  The Company distinguishes itself in its markets by
emphasizing a culture in which customers are the highest priority in all
aspects of the Company's operations.  Ongoing employee training is focused on
customer needs, responsiveness and courtesy to customers.  The Company's
marketing efforts and operating practices emphasize the Company's ties to the
local communities it serves, and its commitment to providing the highest level
of personalized service.

LENDING ACTIVITIES

The Company's loan portfolio consists primarily of commercial loans,
agricultural loans, real estate mortgage loans, residential real estate and
other construction loans, consumer installment loans and bank card loans.  At
December 31, 1995, the Company had total loans and leases outstanding of
approximately $144 million, which equals 87.8% of the Company's total deposits



                                       5

                         UNITED SECURITY BANCORPORATION

and 75.0% of its total assets.  $103 million of these loans were originated by
USB and $39 million were originated by HSB.  At December 31, 1995, virtually
all of the loans held by the Company were to borrowers within the Banks'
principal market areas.

The following table sets forth the composition of the Company's loan portfolio
at December 31, 1995, 1994, and 1993.

</TABLE>

Commercial Loans.  Commercial loans primarily consist of loans to businesses
for various purposes, including revolving lines of credit, equipment financing
loans and letters of credit.  These loans generally mature within one year,
have adjustable rates and are secured by inventory, accounts receivable,
equipment or real estate.  The Company also classifies commercial construction
loans, which may have maturities in excess of one year, as commercial loans.

Agricultural Loans.  Agricultural loans primarily consist of farm loans to
finance operating expenses.  These loans generally mature within one year, have
adjustable rates and are secured by farm real estate, equipment, crops or
livestock.  Since agricultural loans present certain risks not associated with
other types of lending, the policy of the Banks has been to make such loans
generally only to agricultural producers with diverse crops, thereby mitigating
the risk of loss attributable to a crop failure or the deterioration of
commodity prices.  The company has also reduced its loan exposure to
timber-related borrowers in northeastern Washington in recent years, due to
consolidation of the timber industry in the area generally and the gradual
elimination of some timber-related businesses attributable to increased
environmental concerns.

Mortgage Loans.  Mortgage loans include various types of loans for which the
Banks hold real property as collateral.  At December 31, 1995, mortgage loans
included approximately $17.8 million of adjustable and fixed rate first
mortgage loans secured by one to four family residential properties,
approximately $3.9 of second mortgage loans secured by one to four family
residential properties, approximately $4.5 million in mortgage loans secured by
multifamily (five or more) residential properties.  Mortgage loans typically
mature in one to five years and require payments on amortization schedules
ranging from one year to twenty years.

Construction Loans.  Construction loans are made to individuals and contractors
to construct primarily single-family principal residences.  These loans have
maturities of three months to six months.  Interest rates are typically
adjustable, although some fixed-rate loans are made.  The Company's policy is
to require that a permanent financing commitment be in place before a
construction loan is made to an individual borrower.

<PAGE>   7
                         UNITED SECURITY BANCORPORATION

Consumer and Other Loans.  Consumer loans are primarily automobile and home
equity loans.  Consumer loans generally have maturities of five years or less,
and fixed interest rates.  Other loans consist of personal lines of credit and
bank card advances.  Personal lines of credit generally have maturities of one
year or less, and fixed interest rates.  Bank card advances are generally due
within 30 days and bear interest at rates that vary from time-to-time.

INTEREST RATES.  The interest rates charged on loans vary with the degree of
risk and amount of the loan, and are further subject to competitive pressures,
money market rates, the availability of funds and government regulations.  
Approximately 45% of the loans in the Company's portfolio have interest rates
that float with the lending reference rate (which is in turn based on
various indices such as the rates of interest charged by money center banks).

LENDING AND CREDIT MANAGEMENT. USB and HSB each folllow loan policies, which
have been approved by each Bank's board of directors and are overseen by the
Company.  The policies establish levels of loan commitment (by loan type) and
credit review and grading criteria, and other matters such as loan
administration, loans to affiliates, costs, problem loans and loan loss
reserves, and related items.  Loans are typically reviewed and graded on a
monthly basis.

All loan applications are processed at the Banks' branch lending offices.  All
loan applications are approved by designated officers in accordance with the
respective guidelines and underwriting policies of the Banks.  Credit limits
generally vary according to the type of loan and the individual loan officer's
experience.  The maximum current loan limits available to any one individual
vary from $25,000 per loan to $300,000 per loan.  In addition, five individuals
currently can combine their credit authority, to a maximum of $750,000 for USB
and $500,000 for HSB, with respect to certain loans.  Loans in excess of
$750,000 for USB and $500,000 for HSB require the approval of the board of
directors of the lending Bank.

Under applicable federal and state law, permissible loans to one borrower by
either of the Banks are also limited.  As of December 31, 1995, the Banks, as a
matter of policy, do not extend credit to any single borrower in excess of
$2,540,000 and $1,000,000 for United Security Bank and Home Security Bank,
respectively.

To accommodate borrowers whose financing needs exceed their lending limits,
both Banks can sell loan participations to each other or to outside
participants.  At December 31, 1995, 1994 and 1993, the outstanding balance of
loan participations sold outside the Company were $22,365,000, $23,383,000, and
$19,078,000, respectively.

SECONDARY MORTGAGE SALES.  USB Mortgage also sells mortgage loans in the
secondary market to various mortgage underwriters and other financial
institutions.  The Mortgage Company sells fixed-rate, single-family residential
loans in order to decrease the amount outstanding of such loans and also sells
adjustable rate residential loans in order to increase the weighted average
yields of the portfolios.  In 1995, the Mortgage Company sold $9.6 million
mortgage loans, consisting of $8.4 million of fixed-rate residential loans and
$1.2 million of adjustable rate residential loans.  Fees received on such sales
are included in interest and fees earned on loans, and accounted for
approximately .8%, 1.7%, and 4.6% of such interest and fees in each of the
three years ended December 31, 1995, 1994, and 1993, respectively.  Such loans
are typically sold on a servicing released basis, meaning the Company does not
retain mortgage servicing responsibilities.

</TABLE>

The Company's nonperforming loans consist of nonaccruing loans, which are loans
that are past due over 90 days, other than loans that are adequately
collateralized and in the process of collection.  No interest is taken into
account unless received in cash or until such time as the borrower demonstrates
an ability to resume payments of principal and interest.  Interest previously
accrued, but not collected is reversed and charged against income at the time
the loan is placed in nonaccrual status.  In 1995 the Company adopted Statement
of Financial Accounting Standards (FASB) No. 114, Accounting by Creditors for
Impairment of a Loan, as amended by FASB No. 118, Accounting by Creditors for
Impairment of a Loan--Income Recognition and Disclosures.  These Standards
require that impaired loans be measured to reflect the fair value of collateral.
Nonaccrual loan and accruing loans more than 90 days delinquent are considered
impaired loans.  Loans classified impaired are evaluated as part of management's
allowance for loan loss adequacy review.  The fair value of the collateral is
evaluated to determine if a specific allowance for loan loss is needed for
impaired loans.  See note 5 to the Consolidated Financial Statements.

Other real estate owned (OREO) includes property acquired by the Banks in
foreclosure proceedings or by acceptance of a deed in lieu of foreclosure.  When
title is obtained to the property it is classified with OREO.  Such property is
carried at the lower of cost or estimated fair market value at the time it is
acquired by the Banks, and loan losses arising from the acquisition are charged
against the allowance for loan loses.  The OREO of the Company had a book value
of $370,000 as of December 31, 1995, consisting primarily of commercial
property.

ANALYSIS OF ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses represents management's recognition of the risks
of extending credit and its evaluation of the quality of the loan portfolios of
the Banks.  The allowance is maintained at levels considered adequate by
management to provide for anticipated loan losses, and is based on management's
assessment of various factors affecting the loan portfolios, including problem
loans, business conditions and loss experience, an overall evaluation of the
quality of the underlying collateral, holding and disposal costs, and the cost
of funds of the Company.  The allowance is increased by provisions charged to
operations and is reduced by loans charged off, net of any recoveries.

The decline in real estate market values in many parts of the country and the
significant losses experienced by many financial institutions in the late
1980's, have resulted in increased regulatory scrutiny of the loan portfolios
of financial institutions such as the Company and the Banks, particularly with
respect to commercial real estate and multi-family residential real estate
loans.  Management of the Banks periodically reviews the status of loans that
are contractually past due and the net realizable value of the collateral
securing such loans, and establishes reserves through the provision of loan
losses where ultimate collection of such loans is questionable.  The provision
for loan losses also reflects a general allocation of unanticipated losses
based in part on the size of the Bank's loan portfolio and management's
assessment of economic conditions within the Bank's service area.  Management
believes that the asset quality of the Banks' loan portfolios has significantly
improved and that the provision for loan losses and allowance for loan losses
is adequate.

The following table sets forth information regarding changes in the Company's
allowance for loan losses for the years ended December 31, 1995, 1994 and 1993.

Yields were determined by dividing aggregate annual interest income for 1995 by
aggregate book value at December 31, 1995.  The yields for tax-exempt
securities have been computed on a full tax equivalent basis using an assumed
tax rate of 34%.  Maturities of mortgage-backed securities are estimated and
are based on the average lives of the underlying mortgage loans, as adjusted to
incorporate prepayment assumptions.

DEPOSITS

The Company's primary source of funds has historically been customer deposits.
The Banks strive to maintain a high percentage of noninterest-bearing deposits,
which are low cost funds and result in higher interest margins.  At December
31, 1995, 1994, and 1993, the Company's ratios of noninterest-bearing deposits
to total deposits were 15.7%, 15.6%, and 18.6%, respectively.

The Company offers a variety of accounts designed to attract both short-term
and long-term deposits from its customers.  These accounts include negotiable
order of withdrawal ("NOW") accounts, money market investment accounts, savings
accounts, and certificates of deposit and other time deposits.
Interest-bearing accounts earn interest at rates established by management of
the Banks, based on competitive market factors and management's desire to
increase or decrease certain types or maturities of deposits consistent with
the Banks policies.  The Company traditionally has not sought brokered deposits
and does not intend to do so in the future.

The following table sets forth the average balances for each major category of
deposit and the weighted-average interest rate paid for deposits in 1995, 1994
and 1993.

COMPETITION

The Company faces strong competition, in attracting deposits and in originating
loans from other commercial banks, savings and loan associations, mutual
savings banks and credit unions, all of which exist in the Banks' service areas
and many of which have greater financial resources than the Company.  The
Company aggressively competes in its market areas with these other institutions
and financial intermediaries in all phases of its operations.

USB competes for deposits and banking business in northeastern Washington from
seven locations in Chewelah, Colville, Kettle Falls, Ione, and Spokane.  The
bank's market area encompasses Stevens, Ferry, and Pend Oreille Counties, and
the northern and eastern portions of Spokane County.  USB competes against two
commercial banks and one mutual savings bank in Stevens County, one commercial
bank and one credit union in Ferry County and two commercial banks and one
credit union in Pend Oreille County.  In Spokane County, USB competes against
approximately seven commercial banks, one mutual savings bank, several credit
unions and savings and loans.

HSB serves customers in southeastern and southcentral Washington from locations
in Sunnyside, Prosser, and Yakima.  The bank's market area encompasses portions
of Benton and Yakima Counties.  HSB competes against commercial banks, savings
and loans, and credit unions in its market area.

LEGAL PROCEEDINGS

Periodically and in the ordinary course of business, various claims and
lawsuits are brought against the Company or the Banks, such as claims to
enforce lines, condemnation proceedings on properties in which the Banks hold
security interests, claims involving the making and servicing of real property
loans and other issues incident to the business of the Company and the Banks.
In the opinion of management, the ultimate liability, if any, resulting from
such claims or lawsuits will not have a material adverse effect on the
financial position or results of operations of the company.

EMPLOYEES

As of December 31, 1995, the Company had 146 employees, of which 63 were
employed by USB, 39 were employed by HSB, 18 were employed by USB Insurance, 3
were employed by USB Leasing, 17 were employed by USB Mortgage, and 6 were
employed by the Parent Company, United Security Bancorporation. None of the
Company's employees are covered by a collective bargaining agreement.
Management believes relations with the Company's employees are good.  United
Security Bancorporation is located at 9506 N. Newport Hwy., Spokane, WA 99218
and the telephone number is 509-467-6949.

The Company and its banking and nonbanking subsidiaries are extensively
regulated under federal and Washington law by the Board of Governors of the
Federal Reserve System (the "Federal Reserve Board"), the Federal deposit
Insurance Corporation, and the Comptroller of the Currency, the banking and

the Washington Insurance Commissioner.  The laws and regulations administered
by these regulatory authorities are primarily intended to protect depositors
and other customers of the Company and its subsidiaries, and not security
holders of the Company.  Any change in applicable laws, regulations or
regulatory policies may have a material effect on the business operations and
prospects of the Company and its subsidiaries.

The Company is a bank holding company registered under Washington law and the
Bank Holding Company Act of 1956, as amended, and is subject to regulation,
supervision and examination by the Federal Reserve Board and the Washington

<PAGE>   17
                         UNITED SECURITY BANCORPORATION

The Company has adopted a dividend policy which is periodically reviewed and
revised by the Board of Directors.  Historically, the goal of such policy was to
pay dividends at levels established during past years, provided funds were
available and the payment of such dividends did not violate the capital
requirements of the Company or the Banks.  The primary source of funding
dividend payments has been the Banks, which currently pay the Company, in the
form of dividends, approximately 15% of their net annual profits after
establishment of loan loss allowances and payment of taxes.  Funding of
dividends from the Company's other subsidiaries, USB Insurance, USB Leasing, and
USB Mortgage, has been minimal.  The Company expects that future dividends, if
declared, will be paid in the form of stock dividends.

Payment of dividends, including stock dividends, is subject to regulatory
limitations.  Under federal banking law, the payment of dividends by the Company
and the Banks is subject to capital adequacy requirements established by the
Federal Reserve Board and the FDIC.  Under Washington general corporate law as
it applies to the Company, no cash dividend may be declared or paid, if, after
effect to the dividend, the Company is insolvent or the liabilities of the
Company exceed the Company's assets.  Payment of dividends, including stock
dividends, on the Common Stock is also affected by statutory limitations, which
restrict the ability of the Banks to pay upstream dividends to the Company.
Under Washington banking law as it applies to the Banks, no dividend may be
declared or paid in an amount greater than net profits then available, and after
a portion of such net profits have been added to the surplus funds of the Bank.


ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

OVERVIEW

The Company's net income is derived primarily from net interest income of the
Banks, which is the difference between interest earned on their loan and
investment portfolios and their cost of funds, primarily interest paid on
deposits and borrowings.  The Banks have historically enjoyed above average net
interest margins (net interest income divided by average interest-earning
assets), primarily because of loan pricing and because a high percentage of the
Banks' deposits are noninterest-bearing demand deposits, which involve no
interest cost to the Banks.  At December 31, 1995, 15.7% of the Company's total
deposits were noninterest-bearing.  For the years ended December 31, 1995, 1994,
and 1993, the Company's average net interest margins were 6.1%, 6.0%, and 5.8%,
respectively.  See Liquidity and Capital Resources.

Net income is also affected by levels of provisions for loan losses, noninterest
income (primarily service changes on deposits, securities gains or losses and
other operating income) and noninterest expenses (primarily salaries and
benefits, occupancy expenses, data processing costs, FDIC insurance, and other
operating expenses).  For each of the three years ended December 31, 1995, 1994,
and 1993, the provision for loan losses were $317,000, $585,000, and $191,000,
respectively.  Net charge-offs during the year ended December 31, 1995 were
$172,000 as compared to $141,000 and $81,000 during 1994 and 1993, respectively.
For the three years ended December 31, 1995, 1994, and 1993 noninterest income
as a percentage of personnel expenses was 76%, 58%, and 65%, respectively.

NET INTEREST INCOME

The following table sets forth information with regard to average balances of
assets and liabilities for the Company, as well as the total dollar amounts of
interest income from interest-earning assets and interest expense on
interest-bearing liabilities, resultant yields or costs, net interest income,
net interest spread (the difference between the average yield on
interest-earning assets and the average cost of interest-bearing liabilities),
net interest margin and the ratio of average interest-earning assets
to average interest-bearing liabilities.

ASSET/LIABILITY MANAGEMENT

The Company's results of operations depend substantially on its net interest
income. Interest income and cost of funds are affected by general economic
conditions, regulatory policy and competition in the marketplace.  See
"Liquidity and Capital Resources."

the Banks' operating strategies focus on asset/liability management.  The
purpose of asset/liability management ("ALM") is to provide stable net interest
income growth by protecting the Banks' and the Company's earnings from undue
interest rate risk.  Each of the Banks follows an ALM policy for controlling
exposure to interest rate risk.  The ALM policy is established by a committee
in each Bank and is reviewed, approved and administered by the investment
committee of the Company.  In order to control risk in a rising interest rate
environment, management's philosophy has been to shorten the average maturity
of the investment portfolio in order to achieve a more asset sensitive
position, therefore allowing quicker asset repricing. Conversely, in a
declining interest rate environment, the philosophy is to lengthen the average
maturity of the investment portfolio, thereby becoming more liability sensitive.

The ALM policy is also designed to maintain an appropriate balance between
rate-sensitive assets and liabilities in order to maximize interest rate
spreads.  The Banks monitor the sensitivity of their assets and liabilities
with respect to changes in interest rates and maturities, and direct the
allocation of their funds accordingly.  The strategy of each Bank has been to
maintain, to the extent possible, a balanced position between assets and
liabilities, and to place emphasis on the sensitivity of its assets.
Generally, the Banks attempt to maintain liquid assets, in order to meet
funding requirements in the current period, and a ratio of interest income to
average earning assets of 4% to 6%.  At December 31, 1995, the net interest
margins of USB and HSB, respectively, were 5.32% and 4.78%.  Should interest
rates trend upward in the near future, the Company could become more asset
sensitive through the sale of investment securities, although the amount
realized on the sale would be adversely affected by the increased rates.
Management believes there will be less movement in rates on short-term
liabilities such as

savings, negotiable order of withdrawal ("NOW") accounts and money market
accounts in an increasing interest rate environment than in rates on the Banks'
interest-earning assets.

The following table sets forth the contractual payment, maturity or repricing
information, and the resulting interest rate gap, of the Banks'
interest-earning assets and interest-bearing liabilities at December 31, 1995
and the cumulative interest sensitivity gap at December 31, 1995.  The amounts
in the table are derived from internal data from the Company and could be
significantly affected by factors such as changes in prepayment experience,
early withdrawals of deposits and competition. Mortgage-backed securities are
estimated and are based on the average lives of the underlying mortgage loans,
as adjusted to incorporate prepayment assumptions.

Certain shortcomings are inherent in the method of analysis presented in the
foregoing table.  For example, although certain assets and liabilities may have
similar maturities and periods to repricing, they may react differently to
changes in market interest rates. Also, interest rates on assets and
liabilities may fluctuate in advance of changes in market interest rates, while
interest rates on other assets and liabilities may follow changes in market
interest rates.  Additionally, certain assets have features that restrict
changes in the interest rates of such assets, both on a short-term basis and
over the lives of such assets.  In the event of a change in market interest
rates, prepayments and early withdrawals could cause significant deviation from
the stated payments, maturities and repricings.

RESULTS OF OPERATIONS

GENERAL.  The Company's net income increased 90% to $3,751,000 for the year
ended December 31, 1995, from $1,978,000 for the year ended December 31, 1994,
primarily as a result of an increase in net interest income attributed to strong
loan demand. Earnings increased 17% or $651,000 from life insurance proceeds 
net of death benefit expense from the death of a key employee.

Return on average assets and equity were 2.10% and 19.39%, respectively, for

from $163,911,000 as of December 31, 1994.  Total loans increased 17% to
$143,757,000 from $122,765,000 the previous year-end.  The increase in loans
resulted from an increase in loan demand throughout the two Banks service areas.

Return on assets and equity in 1995 were 1.67% and 15.36%, respectively before 
the life insurance proceeds described above. Equity was increased 
$8.5 million in 1995 from the public offering completed in June. See Liquidity 
and Capital Resources for further information.

Deposits increased 12% to $163,791,000 as of December 31, 1995 from $146,629,000
the previous year.  Noninterest bearing demand deposits increased 12% to

                        UNITED SECURITY BANCORPORATION

NONINTEREST INCOME AND EXPENSE.  Noninterest income, which consists of service
charges, commissions, life insurance proceeds, and other fees, increased 67% to
$3,765,000 in 1995 compared to $2,258,000 the previous year.  All categories
were higher in 1995 with life insurance proceeds of $1,030,000 being a
significant portion of the increase.  Noninterest expense increased 31% to
$8,414,000 during 1995 compared to $6,446,000 in 1994.  The Banks opened
branches in downtown Spokane and in Yakima during 1995, also the mortgage and
leasing subsidiaries significantly increased activity during the year. 
Noninterest expense increased $379,000 due to death benefit expense.

YEARS ENDED DECEMBER 31, 1994 AND 1993

GENERAL.  The Company's net income increased 45% to $1,978,000 for the year
ended December 31, 1994, from $1,365,000 for the year ended December 31, 1993,
primarily as a result of an increase in net interest income attributed to
strong loan demand.

Return on average assets and equity were 1.36% and 18.91%, respectively, for
fiscal 1994, as compared to 1.17% and 17.20%, respectively, for fiscal 1993. 
Total assets increased 30% to $163,911,000 for the year ended December 31, 1994
from $125,737,000 as of December 31, 1993.  Total loans increased $33,541,000
during the year, while federal funds sold decreased $1,650,000.  The increase
in loans resulted from an increase in loan demand throughout the two Banks
service areas, and in particular, the Spokane service area.  The decrease in
federal funds sold reflects the utilization of these excess funds throughout
the Banks' service areas to meet increased loan demand.

Deposits increased $32,490,000 to $146,629,000, during the year ended December
31, 1994.  Noninterest bearing demand deposits increased 8% to $22,917,000
during the year.

NET INTEREST INCOME.  The Company's net interest margin was 5.37% in 1994
compared to 4.93% in 1993.  The net interest margin to average earning assets
was 5.99% and 5.75% for 1995 and 1994, respectively.  Net interest income
increased 29% to $7,768,000 for 1994 from $6,021,000 the previous year.

NONINTEREST INCOME AND EXPENSE.  Noninterest income, which consists of service
charges, commissions, life insurance proceeds, and other fees, increased 5% to
$2,258,000 in 1994 compared to $2,149,000 the previous year.  Noninterest
expense increased 9% to $6,446,000 during 1994 compared to $5,918,000 in 1993. 
The increase in noninterest expense was the result of normal inflationary
increases in personnel and occupancy expenses, and start-up costs incurred in
connection with the Spokane Valley branch of USB, which opened in September,
1994.

LIQUIDITY AND CAPITAL RESOURCES

Management believes that the Company's cash flow will be sufficient to support
its existing operations for the foreseeable future.  If the Company needs
additional liquidity, it would be required to borrow or issue additional
securities.  The Company's ability to incur indebtedness is limited by
government regulations and its ability to service borrowings is dependent upon
the availability of dividends from the Banks and nonbank subsidiaries.  The
payment of dividends by the Banks is subject to limitations imposed by law and
governmental regulations.

The Banks may borrow on a short-term basis to compensate for reductions in
other sources of funds.  Bank borrowings may also be used on a longer-term
basis to support expanded lending activities and to match the maturity of
repricing intervals of assets.

The Company's total stockholders' equity increased to $24,863,000 at December
31, 1995, from $12,186,000 at December 31, 1994 and $8,643,000 at December 31,
1993.  At December 31, 1995, stockholders' equity was 12.96% of total assets,
compared to 7.43% at December 31, 1994.  At December 31, 1995, the Company held
cash and cash-equivalent assets of $15.6 million.  At such date, virtually all
of the Company's investment securities ($22 million in aggregate amount) were 
available-for-sale.

The capital levels of the Company and each of the banks currently exceeded
applicable regulatory capital guidelines at December 31, 1995.  During 1995,
the Company issued and sold 1,150,000 million shares of common stock in an
underwritten public offering, which yielded net proceeds to the Company after
deduction of commissions, selling expenses and related offering costs of $8.5
million.  Proceeds from the sale have been allocated among the Company's
subsidiaries and is being used to support the growth of the Company and its
subsidiaries.  Two additional branches were opened in downtown Spokane for
United Security Bank and in Yakima, Washington for Home Security Bank.  The
Company has also expanded its financial services with two of its subsidiaries,
USB Leasing and USB Mortgage.

EFFECTS OF INFLATION AND CHANGING PRICES.  The primary impact of inflation on
the Company's operations is increased asset yields, deposit costs and operating
overhead.  Unlike most industrial companies, virtually all of the assets and
liabilities of a financial institution are monetary in nature.  As a result,
interest rates generally have a more significant impact on a financial
institution's performance than the effects of general levels of inflation.
Although interest rates do not necessarily move in the same direction or to the
same extent as the prices of goods and services, increases in inflation
generally have resulted in increased interest rates.  The effects of inflation
can magnify the growth of assets, and if significant, would require that equity
capital increase at a faster rate than would otherwise be necessary.

                          INDEPENDENT AUDITOR'S REPORT

Board of Directors and Stockholders
United Security Bancorporation
Spokane, Washington

We have audited the accompanying consolidated statements of financial condition
of United Security Bancorporation and subsidiaries as of December 31, 1995 and
1994, and the related consolidated statements of income, changes in
stockholders' equity, and cash flows for the years ended December 31, 1995,
1994, and 1993.  These consolidated financial statements are the responsibility
of the Corporation's management.  Our responsibility is to express an opinion
on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of United Security
Bancorporation and subsidiaries as of December 31, 1995 and 1994, and the
results of its operations, changes in stockholders' equity, and its cash flows
for the years ended December 31, 1995, 1994, and 1993, in conformity with
generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, the
Corporation changed its method of accounting for certain investments in debt
and marketable equity securities effective January 1, 1994, to adopt Statement
of Financial Accounting Standards No. 115, and its method of accounting for
impaired loans effective January 1, 1995, to conform with Statement of
Financial Accounting Standards Nos. 114 and 118.

The consolidated financial statements include the accounts of United Security
Bancorporation (the Corporation) and its wholly-owned subsidiaries, United
Security Bank, USB Leasing, Inc., USB Insurance Agencies, Inc., USB Mortgage
Company and Home Security Bank, after eliminating all significant intercompany
balances and transactions.

NATURE OF BUSINESS:
United Security Bank and Home Security Bank, wholly owned subsidiaries of United
Security Bancorporation, are state chartered commercial banks under the laws of
the State of Washington, and provide banking services primarily throughout
eastern and central Washington.  The Corporation and its subsidiaries are
subject to competition from other financial institutions, as well as
non-financial intermediaries.  The Corporation and its subsidiaries are also
subject to the regulations of certain federal and state agencies and undergo
periodic examinations by those regulatory agencies.

BASIS OF FINANCIAL STATEMENT PRESENTATION:
The financial statements have been prepared in accordance with generally
accepted accounting policies.  In preparing the financial statements, management
is required to make estimates and assumptions that affect the reported amounts
of certain assets and liabilities as of the date of the statement of financial
condition and certain revenues and expenses for the period.  Actual results
could differ, either positively or negatively, from those estimates.

Material estimates that are particularly susceptible to significant change in
the near-term relate to the determination of the allowance for loan losses and
the valuation of real estate acquired in connection with foreclosures or in the
satisfaction of loans.  In connection with the determination of the allowance
for loan losses and other real estate owned, management obtains independent
appraisals for significant properties.

Management believes that the allowances for loan losses and other real estate
owned are adequate.  While management uses currently available information to
recognize losses on loans and other real estate owned, future additions to the
allowances may be necessary based on changes in economic conditions.  In
addition, various regulatory agencies, as an integral part of their examination
process, periodically review the Corporation's allowance for loan losses and
other real estate owned.  Such agencies may require the Corporation to recognize
additions to the allowances based on their judgments of information available to
them at the time of their examination.

SECURITIES AVAILABLE-FOR-SALE
Securities available-for-sale consist of debt and marketable equity securities.
Debt securities primarily of obligations of the U.S. government, state
governments and domestic corporations.  Marketable equity securities consist
primarily of mutual funds whose portfolios consist primarily of U.S. Government
backed debt securities.

NOTE 1.  BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Unrealized holding gains and losses, net of tax, on available-for-sale
securities are excluded from earnings and reported as a net amount in a
separate component of stockholders' equity until realized.  Gains and loses on
the sale of available-for-sale securities are determined using the
specific-identification method.  Premiums and discounts are recognized in
interest income using the effective interest method.

SECURITIES HELD-TO-MATURITY:
Securities for which the Bank has the positive intent and ability to hold to
maturity are reported at cost, adjusted for premiums and discounts that are
recognized in interest income using the effective interest method.

LOANS AND ALLOWANCES FOR LOAN LOSSES:
Loans receivable that management has the intent and ability to hold for the
foreseeable future or until maturity or payoff are reported at their
outstanding unpaid principal balances reduced by any charge-offs or specific
valuation accounts and net of any deferred fees or costs on originated loans,
or unamortized premiums or discounts on purchased loans.  Net deferred fees or
costs are amortized using the interest method over the life of the loan.

Loans are placed in a nonaccrual status when, in the opinion of management, the
collection of additional interest is questionable.  Thereafter, no interest is
taken into income unless received in cash or until such time as the borrower
demonstrates the ability to resume payments to principal and interest. 
Interest previously accrued but not collected is generally reversed and charged
against income at the time the loan is placed on nonaccrual status.

An allowance for probable losses on loans is maintained at a level deemed by
management to be adequate to provide for potential loan losses through charges
to operating expense.  The allowance is based upon a continuing review of
loans, which includes consideration of actual net loan loss experience, changes
in the size and character of the loan portfolio, identification of individual
problem situations which may affect the borrower's ability to repay, and
evaluation of current economic conditions.  Loan losses are recognized through
charges to the allowance.

OTHER REAL ESTATE:
Other real estate comprises properties acquired through a foreclosure
proceeding or acceptance of a deed in lieu of foreclosure, and are initially
recorded at fair value at the date of foreclosure establishing a new cost
basis.  After foreclosure, valuations are periodically performed by management
and the real estate is carried at the lower of cost or fair value minus
estimated costs to sell.  Loan losses arising from the acquisition of such
property are charged against the allowance for loan losses.  An allowance for
losses on other real estate is maintained, when necessary, for subsequent
valuation adjustments on a specific property basis.

NOTE 1.  BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

PREMISES AND EQUIPMENT:
Land is carried at cost.  Premises and equipment are stated at cost less
accumulated depreciation over estimated useful lives, which range from 3 to 25
years.  Depreciation expense is computed using primarily the straight-line
method for financial statement purposes.  Accelerated depreciation methods are
used for federal income tax purposes.  Normal costs of maintenance and repairs
are charged to expense as incurred.

INTANGIBLES:
Intangible assets acquired in the form of goodwill, customer lists and
covenants to not compete are being amortized using the straight-line method
over five to eight years.

INCOME TAX:
The Corporation and its subsidiaries file a consolidated federal income tax
return.  The income tax related to the individual entities is generally
computed as if each one had filed a separate tax return and is based on amounts
reported in the statements of income (after exclusion of non-taxable permanent
differences such as interest on state and municipal securities) and include
deferred taxes on temporary differences in the recognition of income and
expense for tax and financial statement purposes.  Deferred taxes are computed
using the asset and liability approach as prescribed in Statement No. 109,
Accounting for Income Taxes.

PER SHARE AMOUNTS:
All per share amounts have been calculated on the basis of weighted average
number of shares outstanding during each year.  All share and per share amounts
have been adjusted giving retroactive effect to stock dividends and stock
splits.

CASH FLOWS:
For the purposes of presentation in the consolidated financial statements of
cash flows, cash and cash equivalents include cash on hand, amounts due from
banks, certificates of deposit and bankers acceptances with original maturities
of 90 days or less, federal funds sold and overnight deposits with other banks. 
Generally, federal funds are purchased and sold for one-day periods.

RECLASSIFICATIONS:
Certain reclassifications of December 31, 1994 and 1993 balances have been made
to conform with the December 31, 1995 presentation; there were no impact on net
income, earnings per share of stockholders' equity.

RECENT ACCOUNTING PRONOUNCEMENTS:
In 1995, the Financial Accounting Standards Board issued Statement No. 123,
Accounting for Stock-Based Compensation (FASB #123), which established
financial accounting and reporting standards for stock-based employee
compensation plans.  FASB #123 specifies a fair value based method of
accounting for stock-based compensation plans and encourages (but does not
require) entitles to adopt that method

in place of the provisions of APB Opinion 25, Accounting for Stock Issue to
Employees. The new standard is effective for the Corporation starting in 1996.

NOTE 2. ACCOUNTING CHANGES

The Corporation adopted the provisions of Statement of Financial Accounting
Standards No. 115, Accounting for Certain Investments in Debt and Equity
Securities, as of January 1, 1994.  Statement No. 115 requires that management
determine the appropriate classification of securities at the date of adoption,
and thereafter at the date individual investment securities are acquired, and
that the appropriateness of such classification be reassessed at each balance
sheet date.  Since the Corporation does not buy investment securities in
anticipation of short-term fluctuations in market prices, the investment of
debt and marketable equity securities have been classified as either securities
held-to-maturity or securities available-for-sale in accordance with Statement
No. 115.  The January 1, 1994 balance of stockholders' equity was increased by
$29,000 net of the $15,000 related deferred tax effect, to recognize the net
unrealized holding gain on securities on that date.

In 1995, the Corporation adopted Statement of Financial Accounting Standards
(FASB No. 114, Accounting by Creditors for Impairment of a Loan, as amended by
FASB No. 118, Accounting by Creditors for Impairment of a Loan - Income
Recognition and Disclosures.  These Standards require that impaired loans be
measured to reflect the time value of money or the fair value of collateral.
Nonaccrual loans are considered impaired loans and the income recognition for
these loans has been previously described in Note 1 of these financial
statements.  Accruing loans more than 90 days delinquent are also considered
impaired loans.  Loans classified impaired are evaluated as part of
management's allowance for loan loss adequacy review.  The fair value of the
collateral is evaluated to determine if a specific allowance for loan loss is
needed for impaired loans.  Note 5 to the consolidated financial statements
provides further information regarding impaired loans.

NOTE 3. CASH AND CASH EQUIVALENTS

The Banks are required to maintain cash reserves with the Federal Reserve
Bank.  Cash reserve requirements are computed by applying prescribed
percentages to various types of deposits.  When the Bank's cash reserves are in
excess of that required, it may lend the excess to other banks on a daily
basis.  Conversely, when cash reserves are less than required, the Banks borrow
funds on a daily basis.  Such reserve requirements at December 31, 1995 and
1994 were approximately $274,000 and $290,000, respectively.  The average
amounts of federal funds sold and overnight interest bearing deposits with
other banks for the years ended December 31, 1995 and 1994, were $4,390,000 and
$5,158,000, respectively. Similarly, averages of federal funds purchased were
$59,000 and $961,000, for 1995 and 1994, respectively.

accrual of interest has been discontinued amounted to $777,000 and $775,000 as
of December 31, 1995 and 1994, respectively.  If interest on nonaccrual loans
had been accrued, such income would have been $55,000, $81,000, and $35,000 for
1995, 1994, and 1993, respectively.  Interest income on those loans, which is
recorded only when received, amounted to $11,000, $52,000, and $56,000 for
1995, 1994, and 1993, respectively.

NOTE 7. LIFE INSURANCE AND SALARY CONTINUATION PLAN

United Security Bank and Home Security Bank maintain salary continuation plans
for the benefit of certain of their directors, executive officers and other key
employees.  The plans become effective in early 1994 at an initial cost of
$1,913,000 and provided for monthly payments to such persons, or their
designated beneficiaries, for a period of ten years following retirement at age
65, or death prior to retirement.  Amounts payable to eligible participants are
determined by reference to such person's salary or directors' fee as of the
date of each such person's agreement under the plans.

The plans are generally available to most directors, executive officers and
other key employees of the Banks, and vest according to years of service.
Persons employed by the Banks for at least six continuous years prior to the
effective date of the plans are deemed vested with respect to 20% of the salary
continuation benefits available to them, and become vested in an additional 20%
of such benefits for each succeeding year of employment thereafter until the
employee becomes fully vested.  Eligible persons employed by the banks for at
least ten continuous years prior to the effective date of the plans are deemed
fully vested. The Banks' obligations under the salary continuation plans are
funded by prepaid policies of universal life insurance covering the lives of
the plan participants.  The Banks are the beneficiaries of the life insurance
plans.

One of the Banks leases a branch facility under a ten year operating lease with
an additional ten year option from a Director.  Total rental expense on
operating leases amounted to $32,000 for 1995 (Note 17).

Other commitments and contingent liabilities:
The Corporation is a party to financial instruments with off-statement of
condition risk in the normal course of business to meet the financing needs of
its customers and to reduce its own exposure to fluctuations in interest rates. 
These financial instruments include commitments to extend credit, standby
letters of credit and financial guarantees.  Those instruments involve, to
varying degrees, elements of credit and interest rate risk in excess of the
amount recognized in the statement of condition.  The contract or notional
amounts of those instruments reflect the extent of involvement the Corporation
has in particular classes of financial instruments.

The Corporation's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit and
standby letters of credit and financial guarantees written is represented by the
contractual notional amount of those instruments.  The Corporation uses the same
credit policies in making commitments and conditional obligations as it does for
statement of condition instruments.  Unless noted otherwise, the Corporation
does not require collateral or other security to support financial instruments
with credit risk.

The Corporation does not anticipate any material losses as a result of the
commitments of guarantees.

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee.  Since many of the commitments are expect to
expire without being drawn upon, the total commitment amount do not necessarily
represent future cash requirements.  The Corporation evaluates each customer's
creditworthiness  on a case-by-case basis.  The amount of collateral obtained
if deemed necessary by the Corporation upon extension of credit is based on
management's credit evaluation of the counterparty.  Collateral held varies but
may include accounts receivable, inventory, property, plant and equipment and
income producing commercial properties.

Standby letters of credit and financial guarantees written are conditional
commitments issued by the Corporation to guarantee the performance of a
customer of a third party.  Those guarantees are primarily issued to support
public and private borrowing arrangements, including commercial paper, bond
financing and similar transactions.  The credit risk involved in issuing
letters of credit is essentially the same as that involved in extending loan
facilities to customers.

All the Banks' loans, commitments, and commercial and standby letters of credit
have been granted to customers in the Banks' market area.  As such, significant
changes in economic conditions in the State of Washington or within its primary
industries could adversely effect the Company's ability to collect loans.
Substantially all such customers are depositors of the Bank.  The
concentrations of credit by type of loan are set forth in Note 5.  The
Corporation's related party loans and deposits are disclosed in Note 17.  The
Banks, as a matter of policy, do not extend credit to any single borrower in
excess of $2,540,000 and $1,000,000 for United Security Bank and Home Security
Bank, respectively.

As of December 31, 1995 the Banks had unused lines of credit of $27,697,000.
The lines were available for short-term and long-term borrowings.

NOTE 12.  CAPITAL STOCK

STOCK SALES:
In 1995 the Corporation completed its initial public offering and sold
1,150,000 shares of common stock with proceeds of $8.5 million. The Common
Stock has been approved for quotation on the Nasdaq National Market System
under the symbol "USBN". In 1994, the Corporation sold 136,306 shares with
proceeds of $2.2 million through a Board of Directors approved private issue.

STOCK SPLITS AND STOCK DIVIDENDS:
In July, 1995; January, 1995; January, 1994; and January, 1993, the Board of
Directors declared stock dividends of 10%, 10%, 15%, and 15%, respectively. The
Corporation recorded a transfer from retained earnings to common stock for the
value of the additional shares issues. Prior to the public offering book value
was used to record the transfer. Following the public offering market value on
the Board of Directors declaration date was used to determine the amount
transferred from retained earnings to common stock. In July, 1994, the Board of
Directors approved a 2-for-1 stock split. Accordingly, 729,754 shares of stock
were issued. Per share amounts and weighted average shares outstanding have
been retroactively adjusted to reflect stock dividends and the stock split
(Note 20).

NOTE 13.  RESTRICTIONS ON DIVIDENDS AND LOANS

The Banks are subject to state banking regulations relating to the payment of
dividends and the amount of loans that it may extend. Dividends may be paid out
of retained earnings provided that it will not bring the total capital below
the original capital contribution and that the amount in surplus is equal to or
greater than twenty-five percent of the common stock of the Bank. At December
31, 1995 and 1994, the amount of retained earnings of United Security Bank,
available for dividends, amounted to $3,201,000 and $1,465,000, respectively.
Home Security Bank had $882,000 and $694,000 available for dividends at
December 31, 1995 and 1994, respectively.

Certain loans to any person, including liabilities of a firm or association,
cannot exceed twenty percent of the capital and surplus of the Bank. Loans that
are secured or covered by guarantees, or by commitments or agreements to take
over or to purchase the same, made by any federal reserve bank or by the United
States, including any corporation wholly owned directly or indirectly by the
United States, are not subject to these restrictions. No loans can be made
unless the Bank has more than the minimum available funds required by law.

United Security Bancorporation has the full amount of retained earnings
available for dividends.

NOTE 14.  EMPLOYEE STOCK OWNERSHIP PLAN (ESOP) AND PROFIT SHARING 401(K) PLAN

In 1989 United Security Bancorporation adopted an ESOP. An ESOP plan is a form
of retirement plan whereby the Corporation receives a deduction for
contributions to the Plan and the Plan invests all or a portion of the employer
Trust contributions and Trust earnings in stock of the Corporation. The Plan is
qualified under Section 401(a) of the Internal Revenue Code as a stock bonus
plan. Employees 21 years or older become eligible for participation after 1,000
hours or more of service in a plan year, and benefits fully vest after five
years of service. Contributions to the ESOP plan totaled $146,000 and $122,000
for 1995 and 1994, respectively and are based on a percentage of Corporation
earnings. Contributions are allocated pro rata based on eligible annual
compensation on December 31. 

Effective July 1, 1993, the Corporation voted to reinstate the United Security
Bancorporation Profit Sharing 401(k) Plan. There were no employer contributions
in 1995, 1994 and 1993.

NOTE 15.  STOCK OPTION PLAN

In 1995, the Corporation's Board of Directors adopted a stock option
plan, known as the 1995 Incentive Stock Option Plan. The plan provides for the
issuance of incentive stock options to key individuals of the Corporation and
its subsidiaries, including directors and executive officers. Up to 200,000
shares or 8% of the common stock from time-to-time outstanding, whichever is
more, are available for issuance in the form of options under the Plan. The
exercise price of an incentive stock option granted under the Plan may not be
less than 100% of the fair value of the Corporation's common stock on the date
the option is granted, as reported by the NASDAQ Stock Market. A Board of
Directors Compensation Committee and an Executive Remuneration Committee were
formed to direct the granting of the options.

In November, 1995 100,000 common stock options were granted to identified
directors and executive officers at an option price of $12.12 per share. The
options were granted for a five year term from the date of option and may be
exercised anytime prior to that date, subject to conditions prescribed in the
Proxy Statement of the May 24, 1995 Annual Meeting of United Security
Bancorportion. The options were granted at the average price between the high
and low on the NASDAQ Exchange on the last day of the preceding month, before
the date of option. An additional 100,000 shares were maintained for future
distribution. No options have been exercised through December 31, 1995.

NOTE 19. REGULATORY MATTERS

The Banks are subject to various regulatory capital requirements administered
by the federal banking agencies.  The FDIC measures the Banks capital using a
leverage limit together with certain risk-based ratios.  The FDIC requires most
banks it regulates to maintain a minimum leverage ratio, defined as core (Tier
1) capital divided by total regulatory assets of at least 4 to 5 percent.  it
also requires total capital of at least 8 percent of risk-weighted assets; and
Tier 1 capital of at least 4 percent of risk-weighted assets.  Failure to meet
minimum capital requirements can initiate certain mandatory actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements.

FDICIA created a statutory framework that increased the importance of meeting
capital requirements.  FDICIA established five capital categories: well
capitalized, adequately capitalized, undercapitalized, significantly    
undercapitalized and critically undercapitalized.  An institution's category
depends upon where its capital levels are in relation to relevant capital
measures, which include a risk-based capital measure, a leverage ratio capital
measure and certain other factors.  The FDIC has adopted new regulations which
implement this statutory framework.  In order to be well capitalized a bank
must have a ratio of total capital to risk-weighted assets of 10 percent, a
ratio of Tier 1 capital to risk-weighted assets of 6 percent, and a leverage
ratio of Tier 1 capital to risk-weighted assets of 5 percent.  In order to be
adequately capitalized an institution must have ratios of 8, 4, and 4 percent
as described above, respectively.

NOTE 20. SUBSEQUENT EVENTS

STOCK SPLIT-UP
The Corporation's Board of Directors declared a 10% common stock dividend in
the form of a split-up on January 12, 1996 to shareholders of record on January
29, 1996.  The stock was issued on February 5, 1996.  A cash payment of $7,000
was paid for fractional shares based on the closing price on the Board stock
dividend declaration date.  The number of shares outstanding have been restated
at December 31, 1995 to reflect the subsequent issuance of stock.  All weighted
average shares outstanding and per share amounts have also been retroactively
restated.  The intent of the stock split-up was to obtain a reduction in the
unit market price of shares and to obtain wider distribution and improved
marketability of the stock.  No transfer from retained earnings to capital
stock was recorded.

BORROWING
Near the end of January, 1996, United Security Bancorporation borrowed $2.6
million for five years to complete the transfer of Bank real estate to the
Parent Company.  The debt provides for monthly payments of $23,000
including interest at 8.75%. The debt reprices annually at prime plus .25%.
